Citrix ICA - BPC Excel

Hi, 

I am currently trying to record load runner test scripts for Citrix ICA Protocol. My scenario is to Launch  citrix ICA , which opens SAP BPC excel, and perform the business process.  I have got some questions for recording this :

1) Do i need to select single protocol or Multi (if multi - which options to select)

2) Does the bitmap synchronisation happens automatically or do i need to click sync bitmap every time?

3) Citrix ICA - is asking user credentials while launching, is this is ok and do paramaterization or do i need to embed user credentials in ICA file?

Please need your expert advice
